All-dielectric multilayer cylindrical structures for invisibility cloaking

Sci Rep. 2015 Apr 10:5:9574. doi: 10.1038/srep09574.

Abstract

We study optical response of all-dielectric multilayer structures and demonstrate that the total scattering of such structures can be suppressed leading to optimal invisibility cloaking. We use experimental material data and a genetic algorithm to reduce the total scattering by adjusting the material and thickness of various layers for several types of dielectric cores at telecommunication wavelengths. Our approach demonstrates 80-fold suppression of the total scattering cross-section by employing just a few dielectric layers.
